FLUSH VALVE.

Specification of Letters Patent. Patented Apl. 18, 1922- Application filed @otober 27, 1920. Serial No. 419,867.

To all w 710m it may concern Be it known that l, THOMAS L. Tirus, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in a Flush Valve, of which the following is a specification.

This invention relates to a flushing device of the type employing a liquid recep-. tacle for its main valve to modify its movements to its seat, and has for its objects to provide such a construction that the parts may be conveniently assembled, may be economically manufactured, and will be durable. tionary, apertured supportingtube provided with a needle valve and an expanding-disc and having a part disposed in the liquid receptacle, a cylindrical bearing-block slidably mounted on the tube, a flexible ringbetween and normally engaging the bearing-block and expanding-disc. ands. spring permitting v disengagement of the ring from the, disc while the main valve is moving from its seat but which, in connection with the force of water pressure. will cause engagement of the ring with the disc and wall of the main valve while the latter is moving to-its sea whereby this last movement of the valve will be subject to the flow of liquid through the needle valve of the supporting-tube.

Hi the accompanying drawing, Fig. 1 is a view of the device in longitudinal section. Fig. 2 is a side view of a supporting-tube extension, and Fig, 3 is a view of the same in longitudinal section. Fig. 4: is a broken away view of the device. partly in section, showing position of the-main valve while completing its movement from its seat. Fig. 5 is a plan view of the flexible ring or washer. Fig. 6 is a side view showing a part of the supporting-tube. Fig. 7 is a sectional view on line 77 of Fig. 5. Fig, 8 is a sectional view, and Fig. 9 is a plan view of the cylindrical bearing-block.

Referring now to the drawing, numeral 1 indicates a valve housing having a compartment 2 through which'water under pressure may pass from its intake port 3 to its discharge port l by passing the valve seat 5, said housing having a compartment 6 communicating with said intake port and in communication with said discharge port subject to the control of a relief valve 7 dis posed in a passageway 8 which communi- The invention briefly includes a stacates with the compartment 6, said valve 7 normally being disposed upon a valve seat 9, adjacent to said discharge port 4.

In order that the objects first mentioned may be attained, I provide a supportingtube 10 suitably secured to the top and extending within the valve housing, centrally on the valve seat 5. Numeral 11 indicates an extension for the tube 10, said extension having an aperture aformed longitudinally therein, and preferably having a threaded connection for its-inner end wlth said tube, its lower end being provided with a flange b for the support of one end of a spring 12, the upper end of said extension 11 being provided with an inwardly convergent recess or valve seat 18 for a needle valve 1 1 which is disposed in the tube 10 and which may be adjusted longitudinally of said tube, since its upper end has a threaded connection with said tube, as best shown in Fig. 1, said needle valve being for the purpose of controlling the flow of water through the aperture a of said extension 11. I

Thetube 10 is also provided with an annular boss or disc 15, this being formed on nection with the extension 11. and operating as a'val've and also operating as an expanding element since its lower wall d is formed downwardly convergent, as best shown in Fig. 6.

Numeral 16 indicates a main valve formed as a cylindrical receptacle. adapted to contain the tube-extension mentioned, its open, upper end being provided with a flexible, annular cap 17 for a bearing upon the valve seat 5, said member 17 being secured to the top of the valve by means of a lock-nut 18. at '19 is indicated a cylindrical bearingblock which is disposed within the cylindrical receptacle or main valve 16, whereby a lower compartment w and an upper compartment x are provided for said receptacle, said block 19 being in constant on gagement with the upper end of the spring 12, and having apertures 6 formed longitudinally therein and having a central aperture for a slidable mounting on the tube extension 11. Numeral 20 indicates a flexible ring or washer disposed between the valve 15 and the cylindrical block 19 and which constantly engages and is supported by said block.

a In operation, the parts being disposed as its lower end adjacent to its threaded conshown in Fig. 1, if the valve 7 is moved from its seat 9, handle 21 being used for this purpose, water will move through the passageway 8 from the compartment 6, and will move from the intake 3 to the compartment 6 through the annular passageway22, with the result that the main valve 16 will immediately leave its seat 5, this movement of the valve 16 being subject to the action of the spring 12 upon the bearing-block 19,

and the tendency to form a vacuum in the 1 compartment x will cause the block 19 to move a limited distance inwardly of compartment w, the ring 20 also moving with said block and forming an. annular passage way p, as shown in Fig. 4, between said member 20 and member 15, through which water will readily pass to the compartment by moving through the passageways e, the proportion of parts being such that flushing may be quickly accomplished.

On account of the described construction, the movement of the valve 1.6 to its seat, after the valve 7 has been. closed, will not be attended by appreciable vibration. A slidable movement of the valve 16 on the block 19 and ring 20 toward its seat occasioned by water pressure and. aided materially by pressure of the spring against said block, will cause immediate engagement of the ring with member 15, which will prevent water from moving out of the compartment a: through the apertures e, and therefore the water will move from'said compartment :1: tothe compartment w by passing through the aperture a of the extension 11 and through certain apertures 23 of the tube 10,

subject to the control of the needle valve 14.

It will be noted that the ring 20, on account oi? the convergent wall (Z of member will be pressed outwardly against the wall of the receptacle 16 as well as against said wall (Z, which will operate to great advantage while the valve 16 is moving to its seat since it makes an effective .closure of the valve 15" upon its seat 20,, and since the aperture 0: is the only passageway through which water may pass during this move ment of the valve 16, the degree of speed for the latter may be effectively controlled by the needle valve.

It will be noted that the parts required for the device are few and simple and may be conveniently manufactured at, comparatively, a very limited cost, and may be readilyassembled. The operation of the valve is practically noiseless, and on account of the adjustable features mentioned, the dos ing of the main valve 16 may be more or less rapid, as may be required.

Numeral 24: indicates a stop-pin for limitingthe movement of the main valve in one direction, said pin being threaded in a packing nut 25 at the lower part of the valve housing.

lt will be noted that the screw-head for the stem of the needle valve makes a closure of the bore of the tube 10, and while this tube has been specifically mentioned, any other support may be substituted which provides an adjustable mounting for the needle valve, and which permits water to move to compartment 2 from the aperture a when the valve 16 is-moving to its seat.

said valve to form an annular recess or Also it will be noted that the diameter of thedisc 15 should be less thanthat of the bore of.

passageway m therebetween and thereby to tially as described, is preferred, it will be understood, of course, that changes in size. form, proportion. and minor details may be made, said changes to be determined by the. scope oi the invention as claimed.
